CD4512BD3

Signal Switches, Multiplexers, Decoders Overview

The CD4512BD3 is an 8-channel data selector manufactured by Harris Corporation, belonging to the 4000/14000/14000 series of CMOS logic devices. It features a single function with eight input lines and one true output line, housed in a 16-lead ceramic dual in-line package (CDIP16). The device operates within a supply voltage range of 3V to 18V and supports a maximum operating frequency of 2MHz at nominal supply conditions. It is designed for synchronous operation with a load capacitance rating of 50pF and functions reliably across an extended temperature range from -55°C to +125°C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the specific part number CD4512BD3 matches the required ceramic DIP16 package configuration. Confirm radiation hardness requirements if applicable, as standard commercial variants may differ from military or space-grade specifications. Ensure compatibility with existing system voltage levels and thermal management strategies given the wide operating temperature range.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when an 8-input multiplexer with a true output is required in a harsh environment. The ceramic packaging offers superior protection against moisture and contamination compared to plastic equivalents. Consider the 2MHz frequency limit and 50pF load capacitance when designing high-speed signal paths to ensure signal integrity and proper switching performance.

Signal Switches, Multiplexers, Decoders Part Context

This component is part of the legacy Harris 4000 series CMOS logic family, which established foundational standards for high-voltage digital circuits. Harris Corporation was a primary manufacturer of these integrated circuits before industry consolidation. The 'BD3' suffix typically denotes the specific ceramic dual in-line package variant produced by Harris, distinguishing it from plastic or other package types within the same logical function family.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Cross-reference with Intersil or Renesas equivalents such as HCC4512B for rad-hard applications. Verify pinout compatibility with Texas Instruments CD4512BE or Harris CD4512BE for plastic package replacements, noting that package material changes may affect thermal and environmental performance.
